A To all 'whom t may concern;-

Be'it known that we, Gnonon LoNnnnss and LnYLANn Roenes citizens of the United States, residing at Clarksburg. inthe count)T 'ofl Harrison and State of West Virginia,

have invented certain new and useful Inrproveinents in, Zinc-Iiuinaoes, of which the following is aspecification.

' The present invention resides in i1nprovements in zine dross refining; furnaces.

An object of the invention is the provision of a zinc dross refining' furnace which is designed to be constructed from lire-brick or vother similar material, so braced and re inforced, as to prevent any disintegration of the Same, therefore insuring the longl life thereof. l

Another object of the invention is the Rprovisionof a vfurnace euch as described having' a plurality of lire boxes and a spiraliiue in communication therewith.

A' further ob'iect oli the invention is the a zinc dross refining furnace having a fire box and chamber into which dross is placed tjo be refined.

Still another object of the invention is the provision of a Zine dross furnace having a series of lire boxes over which is a fchainbe@ for receivingflue surrounding' the saine, the said f lross eharnber harinar an opening therein through, lwhich refined zine can be discharged and a second. opening: extending-abovo the lirst opening from the dross chamber into acon- 10 the inrovision of 'a mno dross relining li'urnace `which will be comparatively simple, and inexpensive to build, reliable and ellic-iont in nso. and readily operated. it being understood in this connection that `various in thc specific details of construction can be resorted to within the scope of the appended claims, without departing from or sacrilicinngany or' 'the advantages ol the` invent-ion.

` With the above and other objects in view this invention resides in the. novel features ol? construction, formations,l combinations,

the dross to be re 30 fined, the Said hre boxes having a splral 0f DENTS to be hereinafter niore f ully described, claimed and illus-- trated in the accompanying drawings, in which:

'.Figure l is adongitudinal sectional view taken through our invention. Fig. 2 is a front elevation thereof with the upper por tion of the stack broken away. Fig. 3 is a `transverse sectional view taken on the line `lll-terrina to the accompanyinnr drawings 11 through which particles The above mentioned lire boxes are shown only in convontil'nial formas their has no bearing1 upon the invention.` 'It will be seen 'that the lire/boxes are provided at the lowlr'sidcs ot the coi'ivolutions of the spiral llue` and that there is one fire box in eaoh of saidcomolutions. It will be Seen that the lnoducts ol" eon'diustion Afrom each lire box i'iasses through the. flue., taking up the products of cou'ibustion from Vthe next slwrccililinI lire bo'x and so on through the entire length ot' the apparatus until passing out tllrounh the stack 1l.

The compartment (l is and real' end walls 12 and 13` the former of which is provided with a suitable open# innl I4 through which dross can be placed' in the omnpartment 6. ,This opening;r M is closcdj b v a door lo. The compartment li and its' surrournlingr shell 7 are braced by the upper and lower channel irons l'dand. 17 and' the spaced vertical channel irons 18.

'll 1e lire boxes 19 as shown :in-conventional forni onlyY and are located in spaced. relation to each other, below the dross ,Chamber 6, and connect-with the lower volution` .of the spiral` llue- 9. ,These tire boxes 19, also serve as cleanont'passages for structure closed by, l front sides of theV eon- Cri the liuc 9, and are provided with the usual openings or door ways '15)'.

downwardly inclined discharge passage 2U extends from the dross compartment through the wall I3 and pro\'ides a means whereby the zinc upon being converted to a molten stale, will runl down the lower inclined side El() of theI compartment (i, through this passage 25p) into the pots or kettles 2i', which when filled can be. removed asilesired, and al any desired temperature. These kettlefs 27 are supported in any suitable manner, oneY form of support beineY indicated at which includes the base 2U having extending therefrom the opposite, vertical end walls 2l and 2Q provided with shoulders QG upon which and upon the upper edges ot'-,

lhe walls '28, the. kettles 27 rest. Located directly under the, passage 29 is a. second parsage l() communicatiug with the extreme right-hand tire. box. rlhis 'passage 4() is adapted to heat the passage. 2li to prevent the metal flowing through said passage 29 from becoming chilled.

An extension projects from the rear wall lili of the t'urnaee and is braced by a bracket 31'. This extension is formed with a n outi 'z ,'dly and downwardly inclined passage 32 which enters the open air above the.

,rearwardly extending lip ill of the said. ex-

tension 25. Any vapors arisingirom the dr. '4s contained within the compartment (i wil;- nass into this passage 32 whereJ they will he condensed and direi-.ted to H-'o-w over the. end ot' thc lip 34 and-into the, pots or bottles 27.

From the foregoing description taken in connection ,Viththc accompanying, drawings, which forma partv of this application,

it vwill be manifest that a dross. zinc furnacel 3. In a zinc drossl lurnaee, a series ot' lire boxes, a. dross compartmentl havingr upper.

and' lower discharge. passages extending' through end wall thereof and a Spiral flue surrounding said dross compartment.

il. A zinc dross furnace comprising n, series ol lire boxes, a dross compartment having; upper andlcwer discharge assages extending' through one end thcreo e stack for said furnace and a spiral flue surrounding said dross compartment and communicating with the fire boxes and stack.

4,. In a zinc dross furnace `Such as described, a dross compartment, a plurality of fire boxes located below Said compartment, a stack extending from. said furnace, and a spiral flue. surrounding the dross compartment and communicating with said stack.

5. In a zinc dross furnace, a dross compartment, a pluralityof fire boxes located 'beneath said compartment, a spiral fine surroundingr said compartment .and in communication with the tire. boxes, a. stack extending from the -furnacc and communicating with said fille, a spelter box at one end of` the furnace, the bottom of said dross compartment being disposed on a slant sloping to vard the spelter box, a plurality of removable. 'kettles located in the. -spelter box, one wall of the. furnace having an opening sloping,r from the lower wall ot the dross com-- partaient into the spelter box, and a second opening sloping downwardly from the upper wall of said dross compartment to the speltcr box.

, (i. A vzinc dross furnace, comprising a dross compartment, aspiral flue. surroundin;r said dross compartment. and a plurality of lire boxes, one, connected to and Communicating with each convolution of said spiral flue. i

7. A zinc dross furnace, comprising a dross compartment, a spiral Hue surround.- ing said dross compartment. and a plurality of fire boxes, one. connected to the lower side of each convolution of said spiral Hue and communicating therewith.

-n testimony whereof We. aix our signatures in presence of two witnesses.
